Carbon Paste (140°C, 50 ohm/sqr/25µm)
Thermoplastic carbon paste that can be printed in a single pass on one screen is a cutting-edge material with multiple applications in the energy and electronics industries. This advanced carbon-based paste delivers excellent conductivity, thermal stability, and printability. Developed using state-of-the-art research and production techniques, it represents a significant advancement in materials science, meeting the growing demand for high-performance conductive materials. To achieve a sheet resistance of 50 Ω/sqr/25µm, the paste requires low-temperature drying at 140°C. Printed structures should be processed for 30 to 60 minutes at 140°C in a convection oven.
